Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Heap-based buffer overflow

EUVDB-ID: #VU16246

Risk: High

CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2018-18335

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to heap-based buffer overflow in Skia when handling malicious input. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Update the affected package thunderbird to version 60.5.1-1.

Vulnerable software versions

Arch Linux: All versions

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Use-after-free error

EUVDB-ID: #VU16255

Risk: Low

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-18356

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to use-after-free error in Skia when handling malicious input. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and cause the browser to crash.

Mitigation

Update the affected package thunderbird to version 60.5.1-1.

3) Spoofing attack

EUVDB-ID: #VU17703

Risk: Low

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-18509

CWE-ID: CWE-451 - User Interface (UI) Misrepresentation of Critical Information (Clickjacking, spoofing)

Exploit availability: No

Description

The vulnerability allows a remote attacker to conduct spoofing attack.

The vulnerability exists due to a flaw during verification of certain S/MIME signatures causes emails can be shown in Thunderbird as having a valid digital signature, even if the shown message contents aren't covered by the signature. A remote attacker can reuse a valid S/MIME signature to craft an email message with arbitrary content.

Mitigation

Update the affected package thunderbird to version 60.5.1-1.

EUVDB-ID: #VU17653

Risk: High

CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2019-5785

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow in the Skia library. A remote attacker can create a specially crafted web page, trick the victim into visiting it, trigger integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected package thunderbird to version 60.5.1-1.
